So, your opinion is XMLVM to be updated to the latest API, in any  
case, and let the programmer deal with multiple versions.
That's the quickest (and easiest?) solution :)
I am thinking though if there is a safer way to do it.
I am completely ignorant at this point, but is there any java compiler  
option to check if the code is older than a specified version?
How this problem is dealt with java libraries?

For general wrappers, it is not bad.
Still there are a lot of methods that need to be tweaked by hand :)
